This 3D-printed iPhone case will increase your Pokémon-catching rate

Pokémon Go is easy enough for anyone to pick up, but if you want to catch 'em all, you'll need to master the art of throwing Poké Balls.

For the most part, catching a Pokémon in the game is as simple as throwing a Poké Ball straight up at the monster and hoping it doesn't escape. You can also throw a curve ball at Pokémon, but that's a more advanced technique.
